CABINET.

pplicatiou filed 'March 26, 1925. Serial No. 18,473.

'iihis invention relates to cabinets, particularly adapted tor use as amounting and enclosure tor radio receiving apparatus.

ln radio receiving apparatus, it is essential that the differentelements be mounted in hired and rigid relation with the result that itis the universal practice to mount the diterent elements upon a mountingmember and then build an enclosing structure or cabinet about the samewith one wall releasably or hingedly connected whereby access may be hadto the elements ot the apparatus within the cabinetl lt is the object ofthe invention to provide an improved constructed and arranged cabinetfor this purpose which is novel and cheap in structure and enhanced inappearance, and which has combined therewith a sound amplifier or hornbuilt into and concealed within the cabinet. c

ln carrying out the invention, l provide a base board upon which thedierent elements ot the apparatus are mounted in fixed position, and ahood to be engaged upon the base to enclose the apparatus carried by thebase, said hood comprising end members and a panel bent to convex andpreferably curved form in cross section interposed between the endmembers, with a sound ampliier or horn arranged and carried within thehood having a sound emitting outlet thereof through the end of the hoodand a sound receiving opening within the hood in operative relation tosound reproducing means forming a part ot the receiving apparatus.

in the drawings accompanying' and torming a part oi? thisspecifica-tion, ll have shown a cabinet embodying my invention whereinFigure l is gian viev. l

Figure 3 is a cross sectional view taken on the line 3 3 of Figure2looking in the direction of the arrowss y Figure 4 is a cross sectionalview taken on the line fir-d of Figure F2 looking in the direition ofthe arrows.

Figure -5 is a pv; ctive view of a bent par n-l engaged in tirs; ood andco-operating with the hood panel to form a sound ampiier vention shownin the drawing, there is provided a mounting member upon which theoperative parts ot a vreceiving apparatus is mounted, comprising a baseboard 8 of rec tangular shape and of greater length than width having aperpendicularly arranged panel 9 secured thereto within one longitudinaledge po ion, to constitute the trent, said base board and panel being otnon-conducting material.

A. top, in the nature of a hood, is engaged upon the base to enclose themechanism mounted thereon or the panel 9. This hooded top comprises apair of end members or walls 10, 11 connected by a pair ot rails 12, 13interposed between the end walls and secured thereto as by anglebrackets 14 with the rail '12 at the ends abutting at the lower rear corner of the end walls, and the bottom flush with the bottom ot the endwalls, while the rail 13 is at the front intermediate the top and bottomof the end walls, said rail being of greater width than thickness withthe width of the rail arranged in a horizontal plane. A panel 15,preferably ot wood veneer, is bent upon itself to form a U-shaped hood,said panel engaging in and closing the space between the end walls andrails. The panel is connected to the end members by engaging the ends ina groove or recess therein conforming to the shape to which said panelis bent, as shown at 16, with the opposite longitudinal edges of thepanel engaging in grooves or recesses extending longitudinally of therails 12, 13, as shown at 17 and 18 Figures 3 aid 4. In assembling thehood, the panel 15 isfirst engaged in the grooves in the end members 10,11 when the rails 12, 13 are adjusted with the longitudinal edges of thepanel engaging in the rail grooves when the rails and ends are securedtogether, as by the angle brackets 14. Bythis arrangement, the panel isheld firmly in place and prevented from becoming warped and distortedfrom climatic conditions when made of wood veneer. The hood comprisingthe connected end members and panel is engaged over the base board 8 andpanel 9 with the ends 10. 11 kengaging at the ends of the panel 9 andthe forward edge portion of the rail 13 seated in an angular port-ion ofthe panel 9, as at 19, forming in effect a shelf extending forward ofthe panel 9. By this arrangement, the hood is adapted to be removablymounted upon the base and held against endwise or forward shiftingmovement on the base, and to position the hood and prevent lateralmovement, suitable means may be arranged on the mounting members toengage in recesses or openings in the hood rail 12 and bot-tom of theends 10, 11. However, the hood is preferably connected to the base to beswung upwardly and rearwardly from the mounting members for which.purpose the hood is hingedly connected to the mounting member or base,as shown at 20.

As stated it is also an object of the invention to combine with thecabinet a sound amplifier built thereinto to be enclosed and concealedthereby. For this purpose, an end wall of the hood, in the presentinstance the en'd 11, is arranged with an opening 21 (Figures 2 and 4).

A panel 22 of trapezium form and preferably yof wood veneer is bentlongitudinally upon itself to substantially U-shape in cross section, asshown in Figure 5, with the opposite longitudinal edges extendingsubstantially in parallel relation. The panel in this form is insertedinto the hood through the opening 21 with the edge at the smaller end inabutting relation to the end wall 10, as at 23, where it is supported bya bracket 24 fixed to said end with the edge at the larger end seated ina recess arranged about the opening 21, as at 25, and the oppositemarginal portions lying in contiguous relation to the inner surface ofthe hood panel 15, as at 26, and in conjunction with said hood panelforming a sound amplifier or resonance chamber within the cabinet. Thelarger opening at the one end of said chamber constitutes the outlet,while thesound receiving inlet to said chamber is through an opening 27in the smaller end of the panel in register with an opening in thesupporting bracket 241 with which a tubular arm 28, preferably oftapered form, communicates, the end of larger diameter of said armengaging in the opening of bracket 24 and retained therein by a wedge 29interposed between the arm and the cabinet end. 10. This arm extends ina direction toward ably mounted on the outer side of the end wall 11 tobe positioned to deflect sound waves in a direction towardl the front ofthe cabinet. This detlector is in the form'of a plate having a surface33 adjacent the outlet of the amplifier chamber of concave form, and ispivotally or hingedly mounted, as at 34, on the end wall l1 to havemovement on a vertical axis. This deflector may also serve as a closurefor the horn to prevent accumulation of dust, etc. therein, and retainedin closed position by a latch 35. It will be obvious that should thedeflector be moved to its entirely open position that the sound will beemitted in a direction longitudinally of the amplifier, while should thevdeflector be adjusted to a partly open position the sound Waves willimpinge against the concave surface 33 and be deflected in a directionin which said surface extends, and also that the sound may be modulatedby the extent to which the deflector is positioned away from the outletof the amplilier.

As stated, the base board is in the nature of a mounting member uponwhich the operative parts of a receiving apparatus are mounted,I

and to facilitate the mounting of electron tubes 3G, (Figures 6 and 7)said base is provided with perforations 37, shown in the presentinstance as three in number, to serve as receiving sockets for saidelectron tubes with contact terminals for electric conductors in theform of spring fingers 38 fixed in a recess within the under surface ofthe base board and disposed aboutsaid opening in predetermined positionand extending radially toward the center of the perforations forengagement of contact pins projecting through the base of the electrontubes, as shown in Figure 7, the electric conductors connected to thecontacts 38 being arranged in recesses 39 in the under surface of thebase board and the latter being provided with perforations 40 for thepassage ofsuch conductors for connection of the electron tubes withother elements of the apparatus mounted upon the base board. To retainthe contacts of the electron tubes in electrical connection witlrthecontact fingers 38, sleeves 4:1 of insulator material, such as bakelite,are fitted in the perforations 37, the

movement ot' said sleeves into the openings being limited by the contactfingers, and the sleeves arl'anged'with angle slots, as shown at 42, forthe engagement ofthe usual pin extending laterally from the'base ofelectron tubes. y

The rail or shelf 13 is arranged with a series ofalined perforations 43for the passage of knobs 44 connected to adjustable parts of theapparatus, such as rheostats, condensers, etc., certain of said knobshaving graduated dials, shown in dotted lines at 45 in Figure 1,connected thereto and arranged below the shelf when the hood is inclosed position and the graduations of which dials are adapted to beobserved through further openings 46 in said shelf.

It will be obvious that various modifications may be made inconstruction and arrangement of parts, and that portions of theinvention may be used without others and come within the scope thereof.
